file) and, in the case of a shared library, the relocatable addresses
will have to be properly resolved/relocated (and then written into) by
the dynamic linker when it actually attaches the given shared library
to the executing process. (Note that on SVR4, you may wish to use the
`-z text' option to the ELF linker, when building a shared library, as
an additional check that you are doing everything right. But if you do
use the `-z text' option when building a shared library, you will get
errors unless the .ctors and .dtors sections are marked as writable
